The relative contributions of ions, electrons and positive holes to the conductivity is described drrough the transport number which is related to a partial conductivity defined by... 

Thermal conductance defines a material s ability to transmit heat measured in watts per square meter of surface area for a temperature gradient of one Kelvin in terms of a specific thickness expressed in meters. Its dimensions are therefore W/m K. 

By definition, a molecular transport junction consists of a molecule extended between two macroscopic electrodes. The nature of the molecule, the environment (whether it is solvated or not), the electrode s shape and composition, the temperature, the binding of the molecule to the electrodes, and the applied field are all variables that are relevant to the measurement, which is usually one of differential conductance, defined as the derivative of the current with respect to voltage.

Properties such as high density and homogenous conductivity define the quality of ceramic targets. Ceramics with nonconductive inclusions exhibit arcing and nodule growth on the target surface, while targets with low density exhibit inferior film properties due to contaminations with different species. 

Electrolyte solutions obey Ohm s law just as metallic conductors do. Thus the current 1 passing through a given body of solntion is proportional to the applied potential difference V. The resistance R of the body of solution in ohms (O) is given by A = VU, where the potential difference is expressed in volts and the cnrrent in amperes. The conductance, defined as the reciprocal of the resistance, of a homogeneons body of uniform cross section is proportional to the cross-sectional area A and inversely proportional to the length 1 ... 

In view of the complexity of the variables in experimental animals studies concerned with establishing models of EMS, a number of investigators have attempted to gain some insight into the pathogenesis of EMS by conducting defined in vitro studies. Some of these studies are reviewed below. 

The conductance of polyelectrolyte solutions can readily be measured with a high degree of precision [22], As a reference, the conductance behavior of simple electrolyte solutions is shown in Figure 1. Flere, A is equivalent conductance defined by... 

Despite these shortcomings, we can see that the best response values are situated near points 5 and 8. For a more detailed investigation, the experimental region was then constrained a little bit more, to increase the number of runs in the most favorable region. A new design was conducted, defined by the constraints 0.5[Pg.362]

For solid bodies the heat flux, q, is directly proportional to the temperature gradient, VO, and the thermal conductivity, k, of the body. The minus sign refers to the direction of the flux, which is opposite to the direction of the temperature gradient. Therefore, if the temperature gradient (for a certain time period) is constant, the thermal conductivity defines the amount of thermal energy that is transmitted within a unit time and through a unit cross-sectional area. The area is perpendicular to the direction of flow. 

The imaginary part of the response is in phase with E and for that reason can be considered as an ac conductivity. As is usual we may formally acknowledge this by writing e" = dipole relaxation processes are responsible and the superscript signifies an in-phase contribution to the total in-phase conductivity defined below. 

The enterprise conducts defined procedures to verify that each requirement and constraint described by the established functional architecture is upward traceable to the validated requirements baseline, and that all top-level system requirements and constraints recorded in the requirements baseline are downward traceable to the functional architecture. 

Translation into Formal Graph of this relationship is made in Graph 3.3 together with the conductance defined by Equation 3.9, in assuming that space is isotropic and the matter of the system is homogeneous. More general cases will be treated later.
